Abstract : Pressure data was obtained to investigate the effect of triple ejector rack (TER) geometry on the nose-down pitch of the M-117 bomb. Twelve modifications to TER-9/A and the design currently used were tested. These modifications consisted of blunt and round nose fairing configurations as well as a change to the aft fairing. Variations in TER geometry appeared to have little effect on the normal force and pitching moment distribution for the bomb. In most cases, noticeable effects were confined to the midsection and tail region of the bomb. Final results indicated that the short, blunt nose fairing configurations produced the best reduction in the nose-down pitching tendency.
